融合D-InSAR和Offset-tracking技术的矿区沉降信息提取
A method for extracting deformation mining subsidence by using D-InSAR and Offset_tracking technology
摘要
Abstract
Mining Subsidence has a characteristics of fast rate and large magnitude.Currently,through using of synthetic aperture radar interferometry (InSAR) technology is difficult to get correct information on the whole basin surface subsidence caused by coal mining.To solve this problem,a new method is proposed which is combined D-InSAR and Offset_tracking technology to extract deformation mining subsidence.Firstly,subsidence basin boundary is obtained and established by using D-InSAR.The subsidence basin edge is generated by Offset_tracking technology.Secondly,the loss-related problems in D-InSAR and the advantages of Offset_tracking are analyzed.Finally,combine with the inversion of the basin center and D-InSAR acquired boundary,the time series deformation value above the working face is obtained.The relative error of maximum subsidence point is from 0.5 ％ to 7.3 ％.The experimental results show that this method can effectively solve the problem which InSAR technology can not monitor large gradient deformation in mining subsidence,.It provides a new idea for the application of InSAR technology in mining subsidence monitoring.关键词
